Answer:
public class Person {
String name;
int age;
String phoneNumber;
public Person(String name, int age, String phoneNumber){
this.name = name;
this.age = age;
this.phoneNumber = phoneNumber;
}
}
Explanation:
The code above is written in Java.
The following should be noted;
(i) To define a class, we begin with the keywords:
public class
This is then followed by the name of the class. In this case, the name is Person. Therefore, we have.
public class Person
(ii) The content of the class definition is contained within the block specified by the curly bracket.
(iii) The class contains instance variables name, age and phoneNumber which are properties specified by the Person class.
The name and phoneNumber are of type String. The age is of type int. We therefore have;
String name;
int age;
String phoneNumber;
(iv) A constructor which initializes the instance variables is also added. The constructor takes in three parameters which are used to respectively initialize the instance variables name, age and phoneNumber.
We therefore have;
public Person(String name, int age, String phoneNumber){
this.name = name;
this.age = age;
this.phoneNumber = phoneNumber;
}
(v) Notice also that a constructor has the same name as the name of the class. In this case, the constructor's name is Person.
Answer:
The class and constructor in C++ is as follows:
class Person {
public:
string name; int age; int phone;
Person (string x, int y) {
name = x; age = y;
}
};
Explanation:
This defines the class
class Person {
The specifies the access specifier
public:
This declares the attributes; name, age and phone number
string name; int age; int phone;
This defines the constructor for the name and age
Person (string x, int y) {
This gets the name and age into the constructor
name = x; age = y;
}
};

Write a function number_of_pennies() that returns the total number of pennies given a number of dollars and (optionally) a number of pennies. Ex: If you have $5.06 then the input is 5 6, and if you have $4.00 then the input is 4. Sample output with inputs: 5 6 4 506 400
Answer:
The function is as follows:
def number_of_pennies(dollars,pennies=0):
return dollars*100+pennies
Explanation:
This defines the function
def number_of_pennies(dollars,pennies=0):
This returns the number of pennies
return dollars*100+pennies
Note that, if the number of pennies is not passed to the function, the function takes it as 0
Answer:
Code is given as:-
#number_of_pennies function with one default argument with pennies as 0 when no pennies parameter is given
def number_of_pennies(dollars,pennies = 0):
pennies = dollars*100 + pennies #one dollar equals 100 pennies so calculate total pennies with this formula
return pennies #return total pennies
print(number_of_pennies(int(input()),int(input()))) #both Dollars and pennies
print(number_of_pennies(int(input()))) #Dollars only

In this chapter, you learned that although a double and a decimal both hold floating-point numbers, a double can hold a larger value. Write a C# program named DoubleDecimalTest that declares and displays two variables—a double and a decimal. Experiment by assigning the same constant value to each variable so that the assignment to the double is legal but the assignment to the decimal is not.
Answer:
The DoubleDecimalTest class is as follows:
using System;
class DoubleDecimalTest {
static void Main() {
double doubleNum = 173737388856632566321737373676D;
decimal decimalNum = 173737388856632566321737373676M;
Console.WriteLine(doubleNum);
Console.WriteLine(decimalNum); } }
Explanation:
Required
Program to test double and decimal variables in C#
This declares and initializes double variable doubleNum
double doubleNum = 173737388856632566321737373676D;
This declares and initializes double variable decimalNum (using the same value as doubleNum)
decimal decimalNum = 173737388856632566321737373676M;
This prints doubleNum
Console.WriteLine(doubleNum);
This prints decimalNum
Console.WriteLine(decimalNum);
Unless the decimal variable is commented out or the value is reduced to a reasonable range, the program will not compile without error.

Memorandum.
To: IT class.
From: Professor Smith.
Date:
Dear students,
The purpose of this memorandum is to let you all know the requirements of an ideal computer room.
1.- The compute room should be a decent, large, space, ready to accommodate the number of students that are going to participate in class.
2.- The proper temperature levels. All the hardware can't stand too much heat. We need ventilators and the right temperature for safety purposes.
3.- The organization of the PCs on every desk must be precise in order to have enough room for everybody's participation and interaction.
4.- Have a proper fire suppression system in place. The risk of fire when working with electronics is considerable.
5.- Access control. The equipment is expensive and must be just for qualified students. Have the proper control-access system to keep the place safe.
Thank you for your attention.
With your cooperation, the computer room should be a place to learn and have fun learning new things.
The _________ attack exploits the common use of a modular exponentiation algorithm in RSA encryption and decryption, but can be adapted to work with any implementation that does not run in fixed time.
A. mathematical.
B. timing.
C. chosen ciphertext.
D. brute-force.
Answer:
chosen ciphertext
Explanation:
Chosen ciphertext attack is a scenario in which the attacker has the ability to choose ciphertexts C i and to view their corresponding decryptions – plaintexts P i . It is essentially the same scenario as a chosen plaintext attack but applied to a decryption function, instead of the encryption function.
Cyber attack usually associated with obtaining decryption keys that do not run in fixed time is called the chosen ciphertext attack.
Theae kind of attack is usually performed through gathering of decryption codes or key which are associated to certain cipher texts The attacker would then use the gathered patterns and information to obtain the decryption key to the selected or chosen ciphertext.Hence, chosen ciphertext attempts the use of modular exponentiation.

Think Critically 5-1 Creating Flexible Storage.
It's been 6 months since the disk crash at CSM Tech Publishing, and the owner is breathing a little easier because you installed a fault-tolerant solution to prevent loss of time and data if a disk crashes in the future. Business is good, and the current solution is starting to get low on disk space. In addition, the owner has some other needs that might require more disk space, and he wants to keep the data on separate volumes. He wants a flexible solution in which drives and volumes aren't restricted in their configuration. He also wants to be able to add storage space to existing volumes easily without having to reconfigure existing drives. He has the budget to add a storage enclosure system that can contain up to 10 HDDs. Which Windows feature can accommodate these needs, and how does it work?
Answer:
The Storage Spaces feature in Windows
Explanation:
The Storage Spaces feature can be used here. This feature was initiated in Windows server 2012 and allows the user store his files on the cloud or virtual storage. This makes it possible to have a flexible storage as there is a storage pool which is updated with more storage capacity as it decreases. The feature also offers storage security, backing up files to other disks to protect against total loss of data on a failed disk.
A hacker gains access to a web server and reads the credit card numbers stored on that server. Which security principle is violated? Group of answer choices Authenticity Integrity Availability Confidentiality PreviousNext
Answer:
Confidentiality
Explanation:
Cyber security can be defined as a preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cybersecurity, there are certain security standards, frameworks, antivirus utility, and best practices that must be adopted to ensure there's a formidable wall to prevent data corruption by malwares or viruses, protect data and any unauthorized access or usage of the system network.
In this scenario, a hacker gains access to a web server and reads the credit card numbers stored on that server. Thus, the security principle which is violated is confidentiality.
Confidentiality refers to the act of sharing an information that is expected to be kept secret, especially between the parties involved. Thus, a confidential information is a secret information that mustn't be shared with the general public.
This ultimately implies that, confidentiality requires that access to collected data be limited only to authorized staffs or persons.
